It is with a very heavy heart that I write this and I apologize for its
length. Please, PLEASE pass this around.
On Monday, June 25, 2007 I took my healthy 9 month old Border Collie Vita
swimming at approximately 6:30 p.m. Vita and two other BC's spent about an
hour and a half diving off the dock, chasing the Water Kong, and running
around.
The temperature that day was just over 90 degrees, but none of the dogs
looked particularly winded or hot.
Vita emerged from the water and looked as if she was going to vomit. She
threw up lake water three times. I wasn't particularly concerned as she took
in a lot of water from retrieving and swimming so much and had seen other
dogs do that in the past without complications.
After the third time throwing up, she lay down and closed her eyes. Her
tongue was hanging out of her mouth and I began to suspect she may have heat
stroke. I immediately placed ice on her stomach and checked her gums.
They were
pink. I took her temperature which was 101.9, still normal. I then called my
Vet who said these conditions did not indicate heat stroke and said I needed
to get emergency medical attention right away.
Vita was not responsive and when I picked her up to put her in the car she
was limp and her eyes were still closed. Her breathing was slow and her
heart was racing. I arrived at the emergency clinic only a half hour from
the time she showed signs of distress. The ER Vet asked me what sorts of
things Vita had been doing all day. I explained that she was crated as I was
gone for the latter part of the afternoon and that upon coming home, the
only other place she went was to the lake.
Vita's eyes were fixed and dilated and the Vet suggested there was already
brain damage. After administering an IV and oxygen, the Vet called me in and
said Vita was not responding and that it appeared that she was suffering
from some kind of toxic poisoning. Her heart rate was 200. He mentioned that
he had recently seen a couple of dogs who died from Blue Green Algae
Toxicity.
I told him that the lake had what appeared to be algae blooms on the surface
of the water. Neither of the other two dogs showed any of the signs that
Vita had and that neither dog took in as much water as Vita apparently did.
We decided to put her on a ventilator overnight and give her a "chance" to
pull through.
When I got home I did a Dogpile.com search of "Blue Green Algae Toxicity in
Dogs" and found some very disturbing information.
-Blooms can occur at any time, but most often occur in late summer or early
fall. They can occur in marine, estuarine, and fresh waters, but the blooms
of greatest concern are the ones that occur in fresh water, such as drinking
water reservoirs or recreational waters.
-Some cyanobacterial blooms can look like foam, scum, or mats on the surface
of fresh water lakes and ponds. The blooms can be blue, bright green, brown,
or red and may look like paint floating on the water. Some blooms may not
affect the appearance of the water. As algae in a cyanobacterial[/URL] bloom die,
the water may smell bad.
-Some cyanobacteria that can form CyanoHABs (Harmful Algal Blooms) produce
toxins that are among the most powerful natural poisons known.
These toxins have
no known antidotes.
-Swallowing water that has cyanobacterial toxins in it can cause acute,
severe gastroenteritis (including diarrhea and vomiting).
-Liver toxicity (i.e., increased serum levels of liver enzymes).
Symptoms of
liver poisoning may takes hours or days to show up in people or animals.
Symptoms include abdominal pain, diarrhea, and vomiting.
-Kidney toxicity.
-Neurotoxicity (outbind://2-00000000B2F83727CF47074CA4EDF7015982BAA6A42F2100/#). These symptoms can appear within 15 to 20 minutes after
exposure. In dogs, the neurotoxins can cause salivation and other neurologic
symptoms, including weakness, staggering, difficulty breathing, convulsions,
and death. People may have numb lips, tingling fingers and toes, or they may
feel dizzy.
Vita had indeed exhibited salivation and signs of weakness, staggering,
difficulty breathing and vomiting.
At 7:00 a.m. on Tuesday, June 26, 2007 I called the Vet and was told that
they took Vita off the ventilator a couple of times during the night and
that she was not breathing on her own. I told him to discontinue the
procedure and to let her go.
I called the DNR here in Michigan and was told that Blue Green Algae didn't
usually appear this time of year and I told the agent that the conditions
were that of late summer in Michigan, very hot for the last two days and
reminded him that Blue Green Algae can appear at any time. He told me not to
panic or to alarm other people. I told him that had someone else panicked,
we wouldn't be having this conversation right now.
Later that morning I found out from a neighbor that her two young boys had
vomiting, diarrhea and stomach cramps last week and her Doctor suggested she
bring in a water sample. I do not know if she did or not.
I also talked to a woman from a neighboring county whose neighbor's dog
ingested a lot of water from a pond and died suddenly a couple weeks ago.
As of this writing, Wednesday, June 27th, I have not heard anything from
Michigan State where I took Vita for a necropsy and toxoligical panel.
For the time being, I would strongly suggest you watch your dogs when
swimming in small lakes and ponds as the potential threat of toxic poisoning
from Blue Green Algae is prevalent. Had I known that algae of any kind was
toxic, you can be sure my dogs wouldn't be swimming anywhere and that Vita,
whose name quite ironically meant "life" in Latin, would be alive today.
Missing you more than you can imagine.
May you rest in peace, Red Top Vita

Thanks Bruce; it's very informative though very sad.

Every year we usually have some dog deaths in Ireland due to algal blooms of this sort that get covered in the news. The blooms can definitely also be toxic to people. The local councils usually will post that a lake or pond is unsafe if they know there is a bloom but many smaller or more remote places would likely go unmarked.

If there is flowing water this type of bloom probably will not be able to happen -- eg a stream. The blooms happen when the water gets very stale, and warms, and nutrient levels start to rise -- runoff from fertiliser can cause spikes too.

It is scary! In summer I stick with the sea and the canal and creek where water is actively moving. There's a big pond in the park near me but I always worry that it will get a bloom in summer months when there's no new water filling it.

My god that is so sad. I have never even heard of algae blooms, my god I will be very careful letting my puppies near any water from now on. I live near lakes but I think they are ok

That is very sad. Here in Australia we too have the problem of blue-green algae in some of the dams at certain times, and the council closes them to public access. I am sure there would be some out of the way dams & ponds too that would go un-noticed.

That is really a tragic and horrifying story, our thoughts are with you and thank you for all of the information you have provided to eliminate the possibility that this could happen to other dogs. So sorry to hear your news...

We have a lake near us and I am sure that it is Blue Algae that is mentioned on the warning notices beside the lake. It tells you not to let dogs swim.
